7 3 Product Description 3 Product Description 3.1 General description The Circuit Sentry Flo-Setter II Balance & Commissioning Valves are precision engineered valves used in closed heating and cooling systems for the distribution of flow in various sections of the system WARNING: California Proposition 65 warning! This product contains chemicals known to the state of California to cause cancer and birth defects or other reproductive harm. This product is not intended for potable water applications. 3.2 Operational limits This product is not intended for use in open systems. An open system is one that is exposed to atmospheric pressure at any point, such as a cooling tower system. The dynamic balancing and commissioning valve ensures easy and reliable balancing of the system, regardless of any fluctuations in the differential pressure of the system. The Circuit Sentry Flo-Setter II limits the maximum flow in the system and can be used in both variable and constant flow systems. The clear GPM flow rate scale on the lockable handle ensures that flow setting is simple and user friendly while the integral P/T ports allow verification of pressure. Valve Maximum Limitations Temperature F ( C) Maximum Working Pressure (kpa) Circuit Sentry Flo-Setter II 14 F (-10 C) to 250 F (120 C) 360 PSI (2500 kpa) 6 Circuit Sentry TM Flo-Setter II Balance & Commissioning Valves with NPT Connections

8 4 Installation 4 Installation 4.1 Installation precautions WARNING: Installation and maintenance must be performed by a qualified professional. CAUTION: The valve can be damaged if improper sweating (soldering) is used with the union connection. Before sweating the union connection to the valve, remove the union nut and O-ring from the valve body, then sweat the union tailpiece with union nut into place. Make sure that all connecting pipe work is water tight. The valve body may be damaged if you overtighten when using PTFE pipe compound or PTFE tape on pipe threads. Avoid damaging the valve operating mechanism by using too much joint compound. Apply compound sparingly to male threads only. Safety rules Service should not be performed on any valve in an active hydronic loop. Before attempting to make any required adjustments, properly isolate and drain the branch loops or system that require service and allow the valves to reach a safe handling temperature and zero pressure condition. Use proper safety equipment including gloves, goggles, or similar tools to avoid contact with system fluids and common hazards. Use proper tools and lifting equipment when installing or servicing the valve. Be sure it is properly supported at all times. Failure to follow these instructions could result in personal injury, death, and property damage. 4.2 Installation guidelines The valves are uni-directional and can be installed in most attitudes. The preferred installation is to mount the valve in the return piping where temperatures are lower and where the sealing gland is less affected by strain. Installation of strainers and isolation valves is recommended. Valves can be used with up to 50% ethylene or propylene glycol mixtures. Be sure to install the valve with the arrow pointing in the direction of flow. There must be a minimum of 4 in (100 mm) access space surrounding the valve. The hydronic system must be properly vented to remove all entrained air. Liquid media containing debris or other particulates should be filtered to avoid damage to or obstruction of the valve, which could cause it to malfunction. Due to the different types of material used, Bell & Gossett Circuit Sentry Flo-Setter II Balance & Commissioning Valves and accessories must be disassembled prior to disposal. Special handling of certain valve components may be required by law or may be sensible from an ecological point of view.

9 4 Installation 4.3 Install NPT connection 1. Apply pipe compound conservatively to male connecting fittings only. Do not overtighten when using PTFE impregnated pipe compound or PTFE tape on pipe threads. Doing so may damage the valve body. Pipe compound should not be used in combination with PTFE thread sealing tape. Using both together can cause leakage and damage the valve or fitting. 2. Check connections for leaks. 4.4 Pipe hanging installations Be aware of water weight in the valve and connected piping when installing your system. Never use the valve as a form of piping support. Support the valves and piping according to the local building code. Failure to follow these instructions may result in property damage. 8 Circuit Sentry TM Flo-Setter II Balance & Commissioning Valves with NPT Connections

10 5 Operation 5 Operation 5.1 Recommended operating procedures Pre-set flow balancing Commission a system 1. Select the appropriate size valve, normally line size, for the required flow rate. The ideal valve selection should operate at about 80% of the maximum flow, enabling them to deliver spare capacity, if required. 2. Set the flow rate of the valve with the presetting scale in the valve handle in accordance with the desired flow rate. 3. Once the valve has been set to the desired flow rate, the knob can be locked in position. Remove the logo cap and tighten with a 2 mm hexagonal key. From this locked position, the valve can be fully closed for isolation purposes and re-opened back to the required set point. WARNING: Burn hazard. Water temperatures higher than 100 F (38 C) can be dangerous. Take all necessary precautions to prevent water or steam leakage. Hot water leakage can occur from readout valves during probe insertion and during hookup of readout kit. Follow the safety instructions supplied with readout probes and readout kits. Installation and maintenance must be performed by a qualified professional. CAUTION: Avoid pipe strain. This can cause breakage and water loss over time. 1. Ensure that the valve is fully open. 2. Using Bell & Gossett Model RP250 B Readout Probes, attach a Bell & Gossett differential pressure readout kit to the readout valves on the desired valve. 3. Measure the pressure differential across the readout valves (P/T ports) in the valve body. Confirm that the value obtained is greater than the minimum value indicated in the valve submittal. If it is not, then investigate the causes and if necessary, report to the designer. 4. Adjust the pre-setting dial for the specified design flow rate. Lock the dial in position and record the setting. 5. Repeat the process for all of the Flo-Setter II valves on the branch. 6. Measure the flow rate indicated at the flow measurement device on the branch. Confirm that the value recorded is equal to the sum of the flows set at downstream Flo- Setter II valves. If this is not the case investigate the causes and, if necessary, report to the designer. If a flow measurement device is not present on the branch, measure the differential pressure across the valve and verify the minimum differential pressure listed in the submittal required to achieve the desired flow rate. 7. Repeat this procedure until all Flo-Setter II valves in the system have been set and their summated flows checked against upstream flow measurement devices or differential pressure verification. 8. Measure the differential pressure across the Flo-Setter II valve on the system index terminal (usually the most remote terminal from the pump). Adjust the pump speed until the pressure differential across this valve is equal to the minimum value indicated in the product submittal.

11 5 Operation 9. Determine the pressure differential at the sensor location. Set the pump speed to control such that the value indicated at the sensor is maintained constant under all conditions. 10.Measure and record the total flow rate, pressure differential and energy consumption at the pump. The Flo-Setter II valve should be fully open when flushing or pressure testing the hydronic system. Strong pressure impacts, or water hammer, can damage closed Flo-Setter II valves. 10 Circuit Sentry TM Flo-Setter II Balance & Commissioning Valves with NPT Connections

12 6 Maintenance 6 Maintenance 6.1 Precautions WARNING: 6.2 Valve inspection All procedures must be performed by qualified personnel. When the process fluid is hazardous, thermal (hot or cold), or corrosive, take extra precautions. Employ the appropriate safety devices and be prepared to control a process media leak. Always wear protective clothing and equipment to safeguard the eyes, face, hands, skin, and lungs from the particular fluid in the line. Periodically inspect the valve for signs of leakage or corrosion. WARNING: Risk for property damage, serious personal injury or death. You must replace the valve if corrosion or leakage is found. 6.3 Reseal the valve The P/T readout ports and drain plugs come pre-assembled with a leading industrial thread sealant, Loctite, and are tightened to appropriate levels. Any field adjustment of factory installed components breaks the original thread seal and could cause leakage. This adjustment necessitates the removal, cleaning, and resealing of those parts per the following instructions. 1. Remove the desired component from the valve. 2. Clean off all of the old thread sealant using a wire brush and gentle abrasion if necessary. If the component or valve appears to have been damaged, replace it. 3. Starting with the second thread of the NPT male valve component, apply a 360º bead of Loctite 567 thread sealant/lubricant as shown. Follow Loctite handling precautions as noted on the product label. 4. If Loctite is not available, it is recommended that you use RectorSeal No. 5 pipe thread sealant for all non-glycol based applications, or any PTFE thread sealing tape. Be sure to follow the manufacturer-specific handling precaution and application instructions as noted on the product label. 5. Thread component into the valve until it is finger tight. 6. Apply torque to the following specification: Size Type Torque, ft-lbs Torque, Nm 1/4 P/T Readout Port 9.0 ft-lbs ft-lbs. / Nm Nm / 0 Circuit Sentry TM Flo-Setter II Balance & Commissioning Valves with NPT Connections 11

13 6 Maintenance 6.4 Attach insulation The use of thread sealants and lubricants on threads also provides lubricity. Overapplication of torque can damage the valve port or component. Thread sealant should not be used in combination with PTFE thread sealing tape. Using both together can cause leakage and damage the valve or fitting. 7. Properly assembled valve components will immediately seal to moderate pressure (6 bar [100 PSI] or less). For maximum pressure resistance, allow the Loctite or RectorSeal No. 5 2 thread sealant to cure for 24 hours. PTFE tape typically does not require curing to achieve maximum pressure resistance. To maximize energy savings, attach insulation to the valve after the system has been balanced. Tape or other acceptable means can be used to secure the insulation to the valve. The insulation must not cover the valve handle. 1 Loctite and Loctite 567 are registered trademarks of Henkel Ag & Co. 2 RectorSeal No.5 is a registered trademark of RectorSeal Corporation. 12 Circuit Sentry TM Flo-Setter II Balance & Commissioning Valves with NPT Connections
